this is the "cbs evening >> schieffer: good evening. scott's on assignment. i'm bob schieffer. the state department issued a travel alert today for americans, mostly for those traveling in the middle east and north africa, and 21 american diplomatic posts in that part of the world, including iraq, egypt, afghanistan, and libya, will be closed on sunday. so far, the government hasn't said much except that it is all connected to al qaeda. but our national security correspondent david martin has learned new details about why the government is taking this so seriously. >> the threat comes from yemen, where the group known as al qaeda in the arabian peninsula has emerged as the most dangerous terrorist organization in the world. the intelligence does not reveal where an attack might occur. analysts believe yemen is the most likely place, but warn it could be anywhere in the arc of mostly muslim countries stretching from north africa to south asia. the threat goes beyond u.s. inn

stlaigzs to include those of other western countries. britain will close its embassy iniemen and urged all its citizens to leave the country. there's no indication what kind of attack might be in the works although al qaeda in the arakian peninsula has specialized in stiewdz bombing. it's master bombmaker built the underwear bomb which nearly blew up an airliner over detroit on christmas day 2009. explosives hidden in printer cartridges and shipped on cargo planes bound for the u.s. were hard to detect, even after authorities had been told where to look. most recount, he designed a new underwear bomb which was handed over to the u.s. by a double agent. at a conference last month, john pistol, head of the transportation security administration, explained why it was so alarming. >> so it was a new type of explosive that we had never seen in either attempts in the u.s. or around the world by

terrorists, so all of our explosive detection equipment which screens over a million checked bags every day-- just in the u.s.-- wasn't calibrated to detect that. >> reporter: but u.s. officials say they have no evidence the current plot is designed to take down airliners bound for the u.s. the embassy closings begin on sunday and could last for a number of days, depending on what more is learned about the threat. the travel alert will remain in effect through the end of august. >> schieffer: all right, thank you very much, david. on another front, cbs news has learned as many as 15 major league players, including the highest paid player in the game, alex rodriguez, will receive heavy penalties will in the baseball drug scandal. and some of them have already agreed not to challenge the lengthy suspensions. don dahler has the latest on that. >> reporter: alex rodriguez warmed up today for a minor league rehab game in trenton, new jersey.

injuries have kept him off the field all season but the league set a deadline on monday for a suspension that may put an end to his career. a source with knowledge of the investigation says several of the players suspected of banned drug use have accepted suspensions, while others continue to negotiate. t.j. quinn is an investigative reporter with espn, who was among the first to report on the story. why is it taking so long for these suspensions to be meated out. >> the delay is baseball trying to get as many players as possible to accept the suspensions without fighting them through arbitration. >> reporter: most players are expected to miss 50 games, but rodriguez is facing more serious punishment. he's not only accused of used banned substances. the league says he recruited other players to use the clinic, obstructed the investigation, destroyed evidence, and tried to intimidate witnesses. we have learned the league is considering two oppositions-- suspending him for rest of this season and next or a lifetime ban. rodriguez plays tonight and tomorrow night in trenton. he will hold a press conference follow the game this evening.

if no suspension is handed down this weekend, the yankees say could rejoin the team in san diego on sunday. bob. >> schieffer: all right, thank you very much, don. america's employers didn't do as much hiring last month as economists were expecting. 162,000 jobs were added. that's the fewest since march. the unemployment rate fell to 7.4%, the lowest in four and a half years, but that was partly because 37,000 people took themselves out of the job hunt and were not counted as unemployed. here's anthony mason. >> reporter: angeline davis has had plenty of time to walk her dog in the year and a half she's been looking for work. does the job market look any better to you? >> until i get a job, to me it's the same. you know what i mean? >> reporter: a former corporate meeting and events plaerp, davis has found some temporary work as a receptionist, but she's been turned down for retail sales

jobs. >>un, people think that you are either over-qualified, they know that you're going to leave as soon as something comes better. i mean, whatever their reasons, they don't-- they don't call me back. >> reporter: while the unemployment rate did dip in july, the employment rate-- that's the percentage of the american population that is working-- has remained largely flat at about 58% since 2010. davis, who is 51 and single, doesn't have children to support, but she worries about losing her apartment. your unemployment benefits have run out? >> as of yesterday i found out. >> reporter: do you know what you're going to do? >> yeah, i usually have a plan "b" in my back pocket and i don't. i don't know what to do. my faith in god-- my bible is a mess, you know. it's -- >> reporter: because you've been using it so much. >> yeah, i've been turning to every promise there can be. it's how i get back. >> reporter: angeline davis is one of more than 4.2 million

americans who have been out of work for more than six months, bob. they still make up 37% of the unemployed. >> schieffer: okay, thanks, anthony. the federal food and drug administration said today that most of the cases in the cyclospora outbreak have been traced to a company in mexico, taylor farms. cyclospora causes stomach illness. 400 cases have been reported in 16 states, most of them in iowa and nebraska. the f.d.a. said taylor farms supplied salad to restaurants in those two states, including red lobster and olive garden. no supermarkets were involved. taylor says the tainted salad is now out of of the supply chain. the trial that has captivated boston is neither its end. the mob boss "whitey" bulger, who is charged with 19 murders, did not take the stand, but he didn't remain silent, either. elaine quijano is there.

appropriate 72 witnesses have testified at the trial of james "whitey" bulger, many describing him as the ruthless boss of boston's irish mob who ordered and participated in hits, all while work as an informant for the f.b.i. but today, the man once on the f.b.i.'s most wanted list told the judge, "as far as i'm concerned, i didn'tigate fair trial, and this is a sham and do what you want with me. that's it. that's my find word." of the it was a crushing disappointment for many who wanted decades for bulger to explain himself and be grilled by prosecutors. >> i have nothing but rage in my heart for whitey bulger, hatred throughout my whole body. >> reporter: tom donahue's father, michael, was allegedly murdered by bulger. his mother, also in court, shout at bulger, "you're a coward." >> i couldn't agree with my mother more. he's the biggest coward to ever walk the streets of the city of boston. >> reporter: bulger fled arrest in 1994 after a tip from a corrupt f.b.i. agent.

16 years passed before agents nabbed him and his longtime girlfriend. they found guns and more than $800,000 stashed inside the walls of his california apartment. bulger's lawyers have acknowledged their client did commit some crimes but deny he was an informant or that he killed women. >> reputation is everything to whitey bulger. >> reporter: boston globe columnist kevin cullen has covered bulger for 30 years. >> the narrative he spent his entire life creating was he is a gangster with scruples and gangsters with scruples don't kill woman and don't become informants. >> reporter: closing arguments are set to begin on monday. bob, jury deliberations are expected to get under way on tuesday. >> schieffer: thank you very much, elaine. in a related story, by the way, authorities said today that stephen rakes, who had hoped to testify against bulger, was found dead after the trial got under way. apparently, he was poisoned. rakes claimed he had been forced to sell his liquor store to bulger but his death,

apparently, had nothing to do with the case. the police are holding a 69- year-old man who owed rakes money and reportedly put poison in his iced coffee. secretary of state john kerry called again today fair peaceful resolution of the crisis in egypt that started a month ago when the military ousted president mohammed morsi, but another bloodbath could be in the offing. hundreds of thousands of morsi supporters are in the streets. the government has told them to disburse, and security forces have them surrounded. clarisa ward is in cairo. >> reporter: at the raba'a la adawiya protest camps, supporters of deposed president mohammed morsi are digging in, bracing themselves for a government offensive that would break up the camp. the government has told the protesters to leave swiftly, promising them a safe exit if they do, but few people here seem to be taking the offer. the longer this stalemate

conditions, ther arg entrenched this protest camp becomes. in the weeks since these protesters first gathered here, we've seen this camp grow dramatically from just a hand full of tents to what now feels like a small town. muslim brotherhood supporters want morsi to be reinstated as president. they vow to fight to the end. deena zacariah spokesperson for the pro-morsi movement tolds you she comes out every day knowing it may be her last. >> i don't have anything. i have a few money and my i.d., because if i will die, they can know who i am. >> reporter: we saw coffins stacked against a wall in anticipation of a violent end to this standoff. >> the people here, not all of them are muslim. now we are all hand in hand. now, cooperating for one aim-- to live freely or to die with dignity.

>> schieffer: clarissa ward in cairo. clarissa, deputy secretary of state bill burns is back in cairo. he was there a couple of weeks ago. now he's back. what's that all about? >> that's right, bob. well, burns is expected to meet with defense minister cece, also the foreign minister, and the muslim brotherhood leaders. he's one of a number of top diplomats applying intense pressure to both sides trying to prevent further violence here in egypt. with the muslim brotherhood expanding its protest and with the government talking ever more forcefully about a possible, imminent crackdown, burns is going to have his work cut out for him. >> schieffer: lrkt clarissa ward in i cairo. thank you, clarissa. what exactly does it mean when the label says gluten free. and cruise ship lines begin posting crime stats when the cbs evening news continues.

>> schieffer: gluten is a protein found in wheat and other grains, and, therefore, in a lot of the food we eat, but it can make some people sick, which is why many products claim to be gluten free. but what exactly does that mean? well, today for the first time, the ft put-- f.d.a. put out a standard definition. >> reporter: 67-year-old stewart levine believes a single bite

from a cookie labeled gluten free led to a painful reaction. >> diarrhea. i just didn't feel right. maybe it was the cookies, even though it is marked gluten free. so i-- i am not eating those keeks anymore. >> reporter: levine has celiac disease. even the tiniest amount of the wheat protein gluten can set off an immune reaction that damages the intestines and other parts of the body. until thowrks there has been no standard definition of what it means for a product to be called gluten free. sales of these products have exploded from 560 million in 2004 to 4.2 billion in 2012. the proposed rules require that a gluten free product contain less than 20 parts per million of gluten. the f.d.a. estimates that 5% of products labeled griewt of gluten free have more than that amount. the government says these new labeling requirements will help ensure individuals with celiac disease are not misexpled are provided with truthful and

accurate information. marg resweiss runs the coag an celiac center in new jersey. what do you think of the new f.d.a. proposals. >> it's a happy day for the celiacs and people following the glient-free diet. it will help remove the confusion when a label doesn't make sense or is incomplete or has conflicting information on it. >> reporter: many people without celiac disease report feel better on a gluten free diet. this is known as gluten sensitivity and has been a major driver in the increase in demand for gluten free products. under the proposed regulations, companies will have one year to comply. >> schieffer: thank you very much, doctor. how safe is the cruise ship you've been thinking of taking? well, the stats you can now find online are next. ,,,,

>> schieffer: if you visit the web sites of the cruise ship lines, you can learn about where they travel, how much they cost, and the amenities they offer, and for the major lines, starting today, you can find out one more thing-- how much crime has been reported aboard ship. here's sharyl attkisson with that. >> reporter: the voluntary postings show many more reports of crimes on u.s. cruise ships than had ever been revealed before. three major cruiseliners-- carnival, royal caribbean, and norwegian cruiselines-- disclosed 232 alleged serious

crimes from october 2010 to june 2013, including six missing u.s. nationals. carnival alone reported five alleged suspicious deaths. the most common allegations were rape and sexual assault. that's substantially more than the 44 cruise ship crimes reported to the coast guard over the past two-and-a-half years. their statistics only reported cases investigated and closed out by the f.b.i. the new higher numbers shows cruise ships are still low risk according to industry spokesman james fox. >> the rate of crimes on cruise ships is appreciably lower than on land. if you're looking for a vacation spot, there's nothing safer than a cruise ship. >> repoprter: kendall carver >> kendall carver doesn't trust the industry to give acras statistics voluntarily. he started the international cruise victims' group after his daughter vanished on day two of an alaskan cruise in 2004. nobody on the ship reported her disappearance, even when the cruise ended and she didn't get

off. >> voluntary does not work. it has to be legislatorred, and that's why we're deeply concerned. we're pleased they're taking one step, but we need to take the next step in & make these requirements mandatory. >> reporter: congress may do just that. senator jay rockefeller, who heads the committee that oversees the cruise industry has propose aid law requiring detailed, mandatory reporting of cruise ship crimes online and on every passenger contract, bob. >> schieffer: thank you very much, sharyl. workers have been scrubbing the lincoln memorial in washington fair week now, but you can still see some traces of the green paint that was tossed on the marble sculpture in an act of vandalism. the woman suspected of doing it was released today to a halfway house. she was arrested monday after a similar incident at the national cathedral. when it is least expected, you can be elected by this candid cameraman.

some of the photos you'd never know they never met, while others capture quite well the inherent awkwardness of cuddling some random dude. >> nice meeting you! >> reporter: even when the subjects seem eager their body language often concedes a certain hesitance-- at least at first. 10 minutes later, though, it's like thanksgiving at aunt margaret's. and that's the really weird thing. >> oh, that's great! >> reporter: yes, richard puts the people in these poses but the sentiment that seems to shine through is real-- at least so say the subjects. >> okay. >> it was sort of awkward, but then sort of night we are probably missing so much about the people all around us. >> this is reiko. >> at first brian sneeden, a poetry teacher, so no rhyme or reason for posing with 95-year- old retired fashion designer reiko ehrman. >> you can come in a little more-- yeah, okay. >> reporter: but eventually, he, too, felt a change. >> i felt like i cared for her. >> reporter: "cared for her."

>> yeah, i felt like it broke down a lot of barriers. >> it was a good feeling >> reporter: pretty much everyone shared that same feeling. >> it was nice to feel that comfort. >> everyone seems to come away with kind of a good feeling. it's kind of lovely. it's lovely. >> reporter: most photographers capture life as it is. but these strangers richard renaldi has captured something much more ethereal and elusive. he shows us humanity as it could be, as most of us wish it would be, and as it was, at least for this one fleeting moment in time. steve hartman "on the road" in new york. >> schieffer: that's the news. sunday on "face the nation" our guests will include congressman paul ryan and senator charles schumer. scott will be along sunday on "60 minutes." i'm bob schieffer in new york. good night. od nig captioning sponsored by cbs ionb captioned by media access group at wgbh access.wgbh.org
